Description
Technical field
The present invention relates to a kind of polyester fiber production technical field, especially a kind of micro denier porous filaments flat FDY long filament
Preparation method.
Background technique
The fine knot that there is existing porous super fine denier FDY intermingled composite fiber specialty fibers group to be formed on the market at present
The vertical configuration state of structure, interfibrous fine space, space three-dimensional, multilayered structure and appearance similar with natural fiber are and general
Fiber is more soft compared to its sense of touch, resilience is more preferable, and natural fiber can be overcome easily to wrinkle, the air-locked disadvantage of staple fibre, separately
Outer fiber is also significantly improved in terms of spreadability, bulkiness and warmth retention property, can assign the super well-pressed soft feeling of fabric, natural sense,
Glutinous and new styles such as dry feeling, certain performances surmount natural fiber, and added value is high, is therefore widely used in middle and high end chemical fibre city
?.
Such as Patent No. 201110432642.5, patent name are a kind of 6 POY/FDY of Multi-hole superfine denier polyamide
Intermingled composite fiber, preparation method and its equipment, it is 0.5~5.0% that mass fraction is added in polyamide 6 slice
Additive, after slice is sufficiently mixed with additive, using 5 grades of screw rod melt extrusion processes, the temperature of 5 grades of screw rods is respectively
249 ± 2 DEG C, 259 ± 2 DEG C, 262 ± 2 DEG C, 260 ± 2 DEG C and 259 ± 2 DEG C；The additive is methacrylic acid
The nanometer randomcopolymer of ester, maleic anhydride and styrene, by weight percentage, the content of methacrylate is 75~
85%, the content of maleic anhydride is 10~12%, remaining is styrene；The cooling and curing process is Xu Leng and circular blow wind
It is cooling；The heating temperature of Xu Leng is 230 ± 2 DEG C；The process conditions of circular blow wind be pressure 490Pa, 22 DEG C ± 2 DEG C of wind-warm syndrome,
Humidity 90% ± 5%, wind speed 0.40 m/s~0.50 m/s；Strand after cooling and solidifying is divided into two beams, it is a branch of through upper
FDY is obtained after oily, pre- network, stretching and thermal finalization；Another Shu Jing is input to the first godet and carries out pre- network after oiling
It is input to the second godet again afterwards and obtains POY, then they are inputted into interlacing jet nozzle simultaneously and carries out compound, rolled molding, be made
6 POY/FDY intermingled composite fiber of Multi-hole superfine denier polyamide；But the porous super fine denier made of the preparation method is poly-
There are following disadvantages for 6 POY/FDY intermingled composite fiber of amide: first, there is lousiness in product, and entire in appearance
Broken yarn is more in production process, and production efficiency is low；Second, dyeing of the product made of this preparation method in the later period is handled
When, the dyeing uniformity of product is not high, and ordinary stain evening ratio can only achieve 90%.
It is solved in view of the above problems, being badly in need of us.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of production broken yarn rate be reduced to 3% hereinafter, and
Guarantee that the even dyeing rate in product later period reaches a kind of preparation method of 95% or more micro denier porous filaments flat FDY long filament.
In order to achieve the above object, the preparation method of a kind of micro denier porous filaments flat FDY long filament designed by the present invention, step
It is rapid as follows:
The first step, using viscosity for the semi-gloss polyester fondant of 0.630~0.640dL/g is primary raw material, by semi-gloss polyester fondant
Filter out extra impurity by the fondant filter that filtering accuracy is 15u, pass sequentially through melt booster pump be pressurized to 180~
After 200bar, then by melt heat exchanger adjusting melt temperature, it is ensured that melt temperature is maintained between 275~280 DEG C, is then passed through
